 we perceive under domestication. 



A most clever trick ! He accepts, provisionally, — 

 although not concurring in, — the truth of his adver- 

 saries' assumption ; he is suffered, then, to work in his 

 false hypothesis (which he would never have been 

 allowed to do, if his adversaries had not been in error 

 in their said assumption) ; and then arrives at his 

 conclusion, which negatives completely the as- 

 sumption by which alone it was possible for him to 

 achieve it ! 



The identity of the several powers, is well shown by 

 the two following quotations, from Darwin's Animals 

 and Plants, &c: 



" Between the powers, which repair a trifling injury 

 in any part, and the power which previously was occu- 

 pied, in its maintenance, by the continued mutation of 

 its particles" (z. e., the reintegration of the tissues), 

 "there cannot be any great difference; and we may 

 follow Mr. Paget in believing them to be the self-same 

 power. As at each stage of growth, an amputated 

 part is replaced, by one in the same state of develop- 

 ment, we must likewise follow Mr. Paget in admitting, 

 ' that the powers of development from the embryo are 

 identical with those exercised for the restoration from 

 injuries'" (p. 430, Vol. ii). 



These remarks show the identity of all the powers 

 of repair, which operate in the same generation in 

 which the organism suffered the departure from its 

 proper type. The following quotation, from Darwin, 

 shows, that the repair which occurs in the next, or 

 succeeding generations (that is, Reversion, or appear-
